Note. The Wechsler Intelligence Scale for Children – Third Edition Verbal Intelligence Quotient (VIQ), Performance Intelligence Quotient (PIQ), and Full Scale Intelligence Quotient (FSIQ) are from Wechsler (1991); the SWR is a combination of the Basic Reading subtest from the WIAT-1 (Wechsler, 1992) and the Word Attack subtest from the WJ-R (Woodcock et al., 1989). All values represent standardized scores. a-CNT and NFnoRD > NF+RD and IRD, p < .001, b-CNT > IRD, p < .001, c-NFnoRD > NF+RD, p < .001, d- NFnoRD > IRD, p < .001, e-CNT > NFnoRD, p = .002.
